Whats the one thing that set you off to want to lose weight?

That I was too lazy to play with my son who was 4 at the time. I was constantly saying "No, maybe later." And then I would never do it later either! After my first year on here when I lost most of my weight we had a big snow storm and we went sledding as a family (something I would always avoid) and were out there for hours up and down the hill. It was a freaking blast and far more meaningful than anything else I ever did when I was sitting on my couch being a lazy turd.

High cholesterol, triglycerides, blood pressure, insulin resistance, hiatal hernia, joint pain, and super morbidly obese at age 38.

I came here to say pretty much the same thing.

Almost hit 300 lbs

Saw the way my grandpa died after a lifetime of smoking and not taking care of himself/stressing himself to death. I would rather pull the plug then die the way he went out.

Diabetes, heart disease, all of those things scare me half to death. I refuse to get them.

Going to be a graduate student, and like it or not how you look is a major factor in how people are going to treat you. I need to limit the amount of things people can try to hold against me.

when i was 7 months post partum a woman at work said "OH I DIDNT KNOW YOU WERE EXPECTING, HERE LET ME HELP YOU WITH THAT BOX!"

A lot of different things, but the biggest thing was watching my step dad struggle with diabetes. I don't want to get diabetes because of my weight... it's scary.

Cracking 300 .. and realizing I was about 1/4" over the biggest size pants kohls sells.

First of all, thank you everyone for sharing your experiences. I read every single one of the responses on this thread.
Some stories brought tears to my eyes because I can relate so easily since I went through many of the circumstances listed here.

Me and myself, I'm a pretty tall girl, at 5'9, and I was an athletic 175lbs in high school at 17.
When I hit 200 at 18, I told myself it was okay, I was tall and "big-boned" and that I didn't look too bad at that point.
Then after high school and hitting college I gained and gained more then the freshman 15, until I hit 250 at 19 and STILL I told myself I have "more cushion for the pushin" and that I was just "curvy" with a big butt/boobs.
It was at 250 (19) that I snagged my amazing, supportive, handsome boyfriend. I figured I still had to look pretty good to snag a hottie, and that my health was fine.
And I was just sooo happy, eat out, drinking, going on dates, turning 21 (alcohol-galore), and finally getting on birth control.
At age 22, in mid-2012, I hit an astonishing 310 pounds on my scale. I couldn't believe it. As I started to analyze and see my life for what it really was.

It was a number of different things that set me off though:
-I noticed that my boyfriend was putting my socks on for me, since I couldn't bend over and touch my toes.
-My little cousin drew a picture of me with her, and drew a circle for my body, and she said "this is your big tummy!"
-My grandma/mom and others asked me if I was expecting and pregnant.
-My size 24 jeans were getting tight. (Since then I now fit into a size 20, comfortably and can squeeze into a size 18 :drinker: )
-My doctor threatened to take me off birth control since I was too heavy. :embarassed: (That scared me!)
-My boyfriend and I had a huge fight which included him pointing out that I kept saying I wanted to lose weight and get healthier and did nothing about it. (Which was absolutely true) :frown:
-And just taking my life day after day, feeling lethargic, with no energy, feeling out of breath when walking through wal-mart and feeling horrible about my looks.
-And lastly, being 22 years old, and not living my life to it's fullest potential I know I can achieve.

My spring clothes not fitting the way I'd like them to.

For me it was walking in the healthfood store, and my feet hurt so bad, I knew I couldn't go on living like this, and that was on August 21, 2011 and I had just turned 51, since then I have lost 50 pounds, but seem to be having a lot of trouble getting the weight off, which is why I joined myfitnesspal.:ohwell:

I have been heavy my entire life. When I was 22 I started having stomach problems. At 24 I had gallbladder surgery because it had literally died in my body and was making me sick. I had been in a lot of pain over those 2 years so I started weight watchers a few months before surgery, before they knew it was my gallbladder because something had to change and I thought maybe it was my weight that was causing the pain. I think I was around 230 at the time. I started losing weight, then had surgery then after recovery I started exercising. I dropped down to a about 180 muscular pounds. It was the first time I had ever truly committed to losing weight I remember how awesome it felt, how happy I was and how much energy I had.

Then I met my husband....and we moved in together....then he lost his job during the economic crash and I got a second job...no time for exercise...then we started planning our wedding....by the time of the wedding I was back up to 220 again over those 3 years. Right after we got married, I was pregnant...and I ended up with hyperemesis til 20 weeks so not exercising because I wasn't eating anything. After birth I was down to 200 and stayed there til after breastfeeding stopped and I shot up to 230 again because I had lost so much muscle mass. Got pregnant again when she was only 7 months old with my second daughter....same thing, hyperemesis, but I didn't lose as much weight...but then....I ended up with IC at 24 weeks and we were afraid we were going to lose her so I was placed on hospital bed rest for a month...that....sucked....and I went home at 28 weeks to home bedrest until 32 weeks. I lost even more muscle mass. After her birth I was so weak. My back was sore all the time, I hated stairs. Now she is 10 months old. I've gotten some strength back, but I'm at 230 again. I'm sick of being so weak and tired all the time and things aching just because I'm not as strong in my body as I used to be. Now If my child would just sleep....this would be much less of a struggle...

A doctor visit. It was actually a follow-up, because I had gotten birth control the previous appointment after complaining about horrible cramps and emotional ups and downs (along with being quite hirsute for a woman). Testosterone was a little high, but my fasting blood sugar was one point short of pre-diabetes. I don't know why, but I asked him if losing weight would really help. He said, "Most likely." I can't really remember why I picked the day I did to start. It was a Tuesday in March. I think the most important part is that I didn't stop. I don't really have any good "before" pictures or anything like that because I didn't make an overly conscious decision to really get on track. I just started trying to eat better and exercise a bit each day, and got enough progress in that going back just couldn't happen anymore.
